Cairsens® NH₃
Miniature solution for real-time continuous NH₃ monitoring
The Cairsens© sensor allows specific pollutant measurement comparable to reference methods. The high quality sensors are renowned worldwide by our customers looking for the newest technologies in air quality monitoring.
Excellent measurement accuracy is achieved by limiting the effect of humidity interference by using a specific and patented inlet filter combined with dynamic sampling.
NH3 micro-sensor
FEATURES AND BENEFITS
- NH3 real-time monitoring
- Very high sensitivity to capture low level gas concentrations (down to ppb)
- Accurate measurement data at a fraction of the cost of Reference Analyzers
- No maintenance required during the Cairsens®’s lifetime
- No need for re-calibration during 12 months
- Embedded USB and UART / ModBus communication ports
- Up to 20 days of 1-minute data storage capacity
- Ultra-small, with close to zero power consumption
- Ready to use and easy to integrate
- Measurements meet European directive 2008/50/EC for indicators
Cairsens® are manufactured in France and calibrated in our metrological laboratory using Standard Reference AQMS monitors. Every sensor shipped includes a calibration certificate.
